Keithley DMM7510 Reference Manual

Model DMM7510
7½ Digit Graphical Sampling Multimeter Reference Manual Section 8:
TSP command reference
DMM7510-901-01 Rev. B / May 2015 8-249
When a mapped event is programmed to clear bits, the bit in the condition register is set to 0 when
the event is detected.
If the event is set to zero (0), the bit is never set.
Example
status.questionable.setmap(0, 4916, 4917)
When event 4916 (the buffer is 0 % filled)
occurs, bit 0 is set in the condition register
and the event register of the Questionable
Event Register. When event 4917 (buffer is
100 % filled) occurs, bit 0 in the condition
register is cleared.

status.request_enable
This attribute stores the settings of the Service Request (SRQ) Enable Register.
Type TSP-Link accessible Affected by Where saved Default value

Usage
SRQEnableRegister = status.request_enable
status.request_enable = SRQEnableRegister
SRQEnableRegister
The status of the service request (SRQ) enable register; a zero (0)
indicates no bits set (also send 0 to clear all bits); other values indicate
various bit settings (0 to 255)
Details
This command sets or clears the individual bits of the Status Request Enable Register.
The Status Request Enable Register is cleared when power is cycled or when a parameter value of 0
is sent with this command.
The instrument returns a decimal value that corresponds to the binary-weighted sum of all bits set in
the register.
